Abstract

Addition of Re, Mo and W to Rh/SiO₂ enhanced the catalytic activity of the glycerol hydrogenolysis using water as a solvent. The modification with Re gave the highest conversion and yield of 1,3-propanediol (1,3-PrD). The optimized Rh-ReO_x/SiO₂ (Re/Rh = 0.5) catalyst maintained high selectivity to propanediols and suppressed C-C bond breaking even under low H₂ pressure and high reaction temperature, where Rh/SiO₂ is rather active to C-C bond breaking. Characterization results indicate the formation of ReO_x clusters attached to the surface of Rh metal particles. This can cause the synergy between ReO_x and Rh, and the glycerol hydrogenolysis proceeds on the interface between Rh metal surface and attached ReO_x species.
